Per spec we shouldn't behave differently depending on how we blocked the
image/object/etc.
This may have made sense in the past when ad blockers were implemented
via nsIContentPolicy, but I think nowadays it doesn't make sense, and
showing fallback is preferred.
There's a couple extra cleanups we can do after this lands, like
removing HTMLImageElement.imageBlockingStatus and simplifying a bit that
code. But I'll do that in a separate bug.

We treat it exactly the same as -moz-broken. The pseudo-class is not
exposed to content, so I don't think we have a reason to keep it around.

When entering or leaving fullscreen in youtube, we spend most of the
restyle time diffing custom properties, under IndexMap::eq.
Turns out that IndexMap equality is not order-aware, and thus you
actually need to make a hashmap lookup for each entry in the map, which
is unnecessarily inefficient.
Instead, just compare the iterators.
See https://github.com/bluss/indexmap/issues/153.

Add -moz-inert and -moz-script-level to the set of internal properties
that aren't included in "all".
-moz-inert may need to be uncacheable in the future if we make it not
change the pointer-events computed value. Left a comment to that effect.

This is strictly better and more flexible, but can change specificity so
have a pref in case it causes trouble. I doubt it will though, the
specificity rules of :is() make more sense, and my gut feeling is that
:-moz-any is not very used on the wild.
Make it early-beta-or-earlier for now to minimize risk, once this is on
nightly for a bit we can enable it everywhere.

Also, for changes in CSS declarations, like changing
cssRules[i].style.color or something, we end up avoiding a lot of the
work we were doing.
This page still trips us in the sense that they add a stylesheet, then
call getBoundingClientRect(), then insert more rules in the stylesheet,
which causes us to rebuild a lot of the cascade data.
We could try to detect appends to the last stylesheet on the list or
something I guess, and avoid rebuilding the cascade data in some cases.
Depends on D85615

As per the following change to the spec:

The additional failure annotation is added because we don't currently treat
text-combine-upright as non-animatable and this patch exposes the existing bug
(bug 1654195).

This fixes performance issues when there's a massive number of rules and
a massive DOM.
Instead of going through all rules for all the DOM, we now look stuff in
hashmaps.

Instead add a pseudo-class that does the expected size="" attribute parsing.
Removing the Gtk-specific rule setting the text color since it doesn't

Forgot to follow up on these two remaining non-standard values that may have
been being used to reset a <meter> or <input type=number> back to its
original appearance, but which telemetry showed no usage of.
Differential Revision: https://phabricator.services.mozilla.com/D83598
Uses of `-moz-appearance: none` are changed to `appearance: none`.
Uses of other values that are simply reverting the appearance back to
its default are changed to `appearance: auto`.
Uses of values in UA sheets that are defining the inherent appearance of
widgets are changed to:
appearance: auto;
-moz-default-appearance: <value>;
since those values are either no longer supported on (-moz-)appearance,
or are still supported but only in some limited form.
There are some uses of `-moz-appearance: textfield` on <input
type=number> elements that are renamed to `appearance: textfield`.

This hooks the "monochrome" media query and co to the
nsIPrintSettings.printInColor setting.
This print setting we're using is not exposed in the print preview UI,
but you can test it setting the print.print_in_color preference to
"false", and then print preview will correctly show up greyscale'd.
Once this lands, the UI folks just have to use it as they see fit :)
I would've liked to add a proper rendering test, but the print reftests
check only whether the PDF text matches.
I could add a test to printpreview_helper.xhtml, but I'm refactoring
that file in bug 1648064 so I'd rather wait a bit and add it in a
separate bug. The test for the media feature should make sure that we
test that code path at least.

By the time we get to iterate over the longhands of a shorthand, we've
already advanced the range iterator, so we look at the next duration and
such, which causes this bug.
I'm seriously baffled that no existing test caught this when it
landed, neither in our internal test suite nor wpt... :/

This avoids arbitrary precision loss when computing REM units and so on,
which is particularly important if we ever change the base of our app
units (but useful regardless).
